Abstract
Effects of mutual interactions between parallel spin electrons on the soliton lattice of a Peierls system are examined in the case of a nearly half-filled band. Soliton lattice solutions of the charge density and the lattice displacements are obtained analytically by use of boson representation of fermion operators in the self-consistent harmonic approximation. The excitation spectra around these soliton lattices are calculated numerically in both cases of rigid and mobile lattices.
